This is the first study reporting the presence of endogenous caffeine, theobromine, and theophylline in all organs of poplar plants. Liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) was used in order to evaluate the... more
Alcohol clamping is a technique that maintains a constant breath alcohol Concentration (BrAC) for prolonged intervals, thereby reducing experimental variance in the timc course of organ exposure to alcohol, when compared with oral alcohol... more
In this study some affinity and dielectric properties of molecularly imprinted (MIP) conducting polymer-polypyrrole (Ppy) based thin films were evaluated. Films of polypyrrole molecularly imprinted with theophylline (MIP-Ppy) and... more
Aminophylline is common used for treating asthma in Indonesia and has narrow therapeutic index. Despite of its affordable price, data on the safety of using aminophylline is still poorly documented. The aims of this study is to analyze... more
The objects of this investigation were (i) to prepare and characterize a new anhydrous theophylline phase that is metastable under ambient conditions, and (ii) to prepare model tablet formulations containing either this metastable... more
Controlled release by oral administration is mainly achieved by pharmaceuticals based on hydrogels. Once swallowed, a matrix made of hydrogels experiences water up-take, swelling, drug dissolution and diffusion, polymer erosion. The... more
A simple, low-cost thin-layer chromatography (TLC) procedure to estimate the quality of simple pharmaceuticals in tablet form is described together with easily built equipment to carry out the test in the field. The approach is... more
